Describe two substances that are useful because of their viscosity

Consider the following reaction at equilibrium. 2co2 (g) 2co (g) + o2 (g) h° = -514 kj le châtelier's principle predicts that the equilibrium partial pressure of co (g) can be maximized by carrying out the reaction a. at high temperature and high pressure b. at high temperature and low pressure c. at low temperature and low pressure d. at low temperature and high pressure e. in the presence of solid carbon

Consider the story you just read. all but one of the choices below indicate that something is living.

If you burn 46.6 g of hydrogen and produce 416 g of water, how much oxygen reacted
